with the hyperjump drive there's no reason for anyone to actually know what's between points A and B.

There has been lots of SF featuring worm-hole networks or pre-existing hyper-space jump points. Have there been any stories featuring two (or more) interstellar societies using disconnected networks who don't interact?

I realise there is no story if the societies don't interact at all, but we could assume occasional meetings two wormholes are STL accessible.
